To all whom it may concern:

Be it known that I, HANS CULEMEYER, a subject of the German Emperor, residing at Peine, in the Province of Hanover and Stateof Prussia, Germany, have invented certain new and useful Improvements in Devices for Unloading Trucks or Freight-Cars by Tilting Them, of which the following is a specification.

This invention relates to means for automatically tilting freight cars laterally and supporting them in such tilted position While discharging their loads.

The object of said invention is to make such action prompt, safe and efiective and to return the cars automatically and readily to their normal position and action on the track.

To this end my invention consists in the construction and combination of parts hereinafter more particularly set forth and claimed.

The drawing shows the invention in several forms of application and execution: Figure 1, the slanted tilting track. Fig. 2, the construction of a torsion-track in perspective. Fig. 8, the application of insidetilting for a coaling-plant for locomotives. Figs. 48, the construction of inside-tilting in combination with a normal track conducted witliin. Figs. 9-11, the simple and double-sided outward-twisting in combination with a normal track.

The advantages of the invention for trade and industry are shortly indicated here:

1. The discharging of trains of any length and at any point of a longer track is possible in few moments without employing a crane or tilting mechanism or any similar machinery except the locomotive of the train.

2. The invention employs only a special arrangement of a track and avoids therefore high expenses for construction, working and maintenance, salary for machinists and so on. It is possible for instance, that the whole train is passed by its own locomotive at the terminal'station into the slanting or tilted position. On account of the very quick unloading of whole trains the in vention promotes the circulation of trucks in a considerable manner. The receiver of bulk-loads spares a good deal of time and salary for unloading.

3. The invention avoids the employment of self-discharging trucks. It makes only use of the usual open trucks and has the advantage, that the open trucks, being in use today, are made fit for use for the method of discharging in question by some small alterations.

a. In combination with a coal-store according to Fig. 3 the invention affords the storage of great quantities of coal, on a cheap ground out of the territory of the great towns along the embankments of the railway-lines. Likewise the recharging of whole trains with coal is possible in a few moments. The importance of the invention in times of war is evident.

5. It is possible for instance by means of a falling gradient, to send trucks loaded with bulk loads in slanting position andin uninterrupted course to several ships to be coaled.

By referring to the above mentioned systematical arrangement of the parts the invention is defined as follows: In Fig. 1 1 is the truck to be unloaded, which is held in the slanting position with both its wheels 2 on the laterally inclined track 3. The truck is prevented from falling over by means of a roll of support 6, which runs on a special rail of support 4. This roll of support, permits in a suitable manner the free play of the springs at one of the lower corners of the car. There may be two such rolls, one being at each corner, to provide for tilting in either direction as needed. By this means the pressure put upon the springs is uniform, that is to say, any turning-momentum, working on the springs of the trucks is prevented. The forces thus produced are shown in the drawing. By virtue of the arrangement, which permits the truck being run into the slanting position, it is possible by simply opening the side-clamps, to effect at any point of the tilting track a spontaneous emptying of the truck. The rails of the tilting track and of the following combinations are fastened to a common angularly bent sleeper 8, which may be produced of any suitable substance. The signification of the rail 5 is explained at another place. It is possible to move the truck on the tilting track for instance by means of a locomotive, running on a normal track, which is arranged parallel to the tilting track.

The trucks to be emptied are transferred to the slanted tilting track either by means of a mechanism for side-tilting or by a gradual torsion of the track. An example for such a twisted track is shown in Fig. 2 in perspective. The track here is gradually tilted by raising the outward rail 3 and lowering the rail of support 4, so that the truck after having run through the twisted track shows the desired slanting position.

The laying down of the twisted. rails can be made in a simple manner by employing the twisting, passes the twisted track angular'sleepers 8, on which the rails are fixed. On account of distinctness only the end-sleepers are shown 7 here. The move ment of the truck on the twisted track can be managed for example by means of a falling 1 gradient, a capstan or a locomotive, running on a normal track, parallel to the twisted track. The normal track, from which the tilting track is branched oti' before i by that side, to which the twisted track has been turned down and runs back into the slanted tilting track at the end of the twisted track. The tilting of the trucks on the twisted track may be managed in the following manner: The locomotive shoves the train to be tilted on to the twisted track, goes back to the switch, runs around the twisted track on the normal track and returns by means of the switch (5 to the "tilting track on the other side of the tilted train to draw the latter out of the twisted track.

It is now advantageous according to Figs. it and 3, to use the rail of support 4 in con- :nection with the rail 5. as a normal track.

Thearrangement is shown in practice according to Fig. 3 providing a coaling-plant for locomotive-servicei The embankment 9 has been secured by old sleepers l2 and the bin 10 has been formed by these and a wooden construction, under which a normal track 11 for receiving coal has been placed. Now in shortest time whole trains with coal can be discharged for purpose of coal-storing along the railway-lines on the outside of the great'towns, and also it is possible, to

coal a great number of locomotives or whole rail of support 4:. At the beginning of the trains at. onceon the lower track 11, and that all without any working machinery and remarkable expenses.

Figs. 4-8 show the possibility to lead a normal track 5 through the midst of an inside-twisted track 34 in such a manner, that the trucks to be discharged can be tilted directly behind the locomotive. This fact is of considerable importance, for by means of this arrangement it is possible to tilt a whole train in slow movementwithout uncoupling the locomotive from the train.

Figs. 47 of the drawing refer to the cross section 1-1 to 1V IV of the ground-plan. Before twisting the twisted track is branched off from the chief-track by means of a simple switch 7, so that the chief-track (normal track) moves in the direction of the port does not approach twisted track (Fig. 4) the rail of support 4 is desirably held a little free from the open space of the normal track for the purpose of permitting free passage to the locomotive and to the untilted trucks. The rail of supthe'roll of support 6, before the truck has been tilted a little downward.

Fig. 7 shows the final position of the tilted truck. Also in this arrangement the rail of support 4 (5) has been used as an outward normal rail.

7 In Figs. 9 to 11 the method of simple and double-sided outward tilting is shown. In opposition to the inside-twisted track, combined with a normal track conducted within (Figs. 4-8), the twisted track 3-3-4 is branched off from the normal track 5-5 so that it moves away from the rail of support 4:. The trucks to be discharged are more easily twisted here than at the insidetwisting above mentioned. It is true that the middle point of truck-coupling is removed farther from the middle point of locomotive-coupling than by employing inside-tilting, so that it would be necessary to couple the trucks to be tilted to the locomotive by a longer coupling-pole. The method of tilting itself is still that of Fig. 2, that is to say: a gradually continuing torsion of a track around a longitudinal axis.

In Figs. 9-11 the rails are fastened for example to angularly bent sleepers 8 of ironconcrete, which are made in special forms corresponding to the degree of twisting. The sleepers of the tilted track itself are of one form. In thearrangement of Fig. 11 the angularly bent sleeper includes a bed of gravel, which is prevented from rolling down by boards of concrete 14.
